Mastering C# and Unity3D

Archive for February, 2010

In my recent work related to events and signals, I had a little discussion about errors that are thrown during the dispatch of an event or signal. I did some investigating to see how EventDispatcher handles this and found something rather surprising.

My last article on Callback Strategies highlighted some pretty severe performance differences between my Runnable strategy, as3signals by Robert Penner, and Flash’s native Event system. My simple Runnable technique had an artificial advantage though: it was not a proper library but instead a little bit of code built right into the test app. Today I’m introducing TurboSignals as an AS3 library making use of the Runnable technique.

I’ve previously covered ways of implementing in my article on Runnables (aka observers) which showed how to call back about 15 times faster than just using a Function object. There are still more ways to call back though and I didn’t cover them at the time. Today I’ll be adding to Function and Runnables by testing Event and the as3signals library by Robert Penner.
